I use VL light with Pentium 2 machines, with much less than 512 in memory. Unless there is something that drags the system on dual boot (perhaps more memory is needed on dual boot), I suggest you try the regular VL 6.0. It is a wonderful distribution that should run fine on your machine. Certainly, unless the dual boot causes problems, it would run find on your machine. I see no reason you are having problems unless, as retired1af says, there is something wrong with your download.

Sounds like a faulty burn. I'd recheck the MD5 sums, ensure they match, then burn at a slower speed.

MD5 sums matched. I use ImgBurn. I burn it at 1x speed. I have tried it on 2 cds Verbatim brand. Same thing happens.Note: I have also tried to boot it on usb stick. Same thing happens.I did search around. I found this thread:http://forum.vectorlinux.com/index.php?topic=11594.0Can you confirm and give a solution?

If you haven't already done so, when time permits, its a good idea to get on gslapt, then update, then mark all records, then execute. This will update your system. Later on, you may or may not want to keep updating generically, as above. Many, after the first update, only update specific programs.
